So I'm gonna buy an R4i Gold from nds-card.com, I'm was planning on just using it on my old DSi but I'm also buying a N3DSXL this week. Seeings as the card is compatible I was wondering if Nintendo can actually tell if we're using a Flash Card on our systems or not. I'm not particularly interested in custom firmware and all that, literally just playing DS games. I'd prefer if my 3DS didn't get bricked or booted offline right after buying it. Thanks Guys.
